How can I make a script in windows for transferring of .stl file from any folder or from CAD software to slicer automatically.

To send from a script or application outside of Slicer, something like this would work:

```auto
Slicer.exe --python-code "slicer.util.loadModel( 'f/pth/to/model.stl' )" 

```

This will launch Slicer and load the requested stl model. To load models into an already launched Slicer, something like [this python snippet](https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Automatically_load_volumes_that_are_copied_into_a_folder) would work within Slicer to have it monitor a folder to automatically load items saved there.
